Abstract

PURPOSE:To eliminate the need for carrying a data loader by incorporating a function generating automatically a reference list between a wire telephone number and a mobile slave set ID number into a radio line controller. CONSTITUTION:A mobile slave set ID is registered in a memory M(x) of an RCU (radio line controller) 2, for example, No.3 is registered in a memory 1(M(1)), No.1 is in a memory 2(M(2)) and No.2 is registered in a memory 3(M(3)). As the registration method, the numbers are stored in the memory in the order of registration from be mobile slave set 4 at the initial setting of the device, the memory M(1) corresponds to an extension connection terminal A, the memory M(2) corresponds to the terminal B and the memory M(3) corresponds to the terminal C. Extension number wires of 300-500 are connected respectively to the extension connection terminals A-C to make the extension 300 to the mobile slave set 4 of No.3 of the content of the memory 1(M(2)). In case of normal call, the link table is being referenced at all times and operated in the device. Thus, the necessity of a data loader is avoided, and the inside of the RCU 2 generates a link table corresponding the extension telephone number with the ID of the mobile slave set automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical field to which the invention pertains The present invention relates to a communication system consisting of a plurality of mobile handsets, a plurality of connection devices, a radio line control device and a private branch exchange that perform line switching control of these devices. , relates to a method for establishing number correspondence between the extension number of a private branch exchange (wired section number) and the unique identification number of a mobile handset (wireless section number).

(2) Prior art and its problems Figure 1 shows a communication system to which the present invention is applied, in which 1 is a private branch exchange (hereinafter referred to as PBX), 2 is a radio line controller (hereinafter referred to as RCU), and 3 is a connection equipment (hereinafter referred to as CE),
4 is a mobile handset (hereinafter referred to as R location), 5 is a wired extension telephone, 6 is a connection line connected from PBXI to RCU 2 and extension telephone 5, 7 is a connection line from RCU 2 to CF 2, 8
is the data loader, 9 is the data loader 8 from RCU2
Shows the connection cable to.

In such a conventional communication system, during wireless communication between extension telephones 5 and R station 4 via PBXI, the R station 4 is portable and can be carried within the service area of the CF 2 at the destination. You can freely make and receive calls even when you are at home.

Therefore, the RCU 2 constantly monitors which CF 2 service area the R station 4 is currently in and files it. It goes without saying that the identification number (hereinafter referred to as ID) of CF2 and the ID of R location 4 are assigned to each individual machine.

In this system, one extension number is assigned to one R station 4. For example, extension number 300, 400
and 500 are Nα1. Nα2. It corresponds to R position 4 of Nα3.

As an example of inter-extension communication, for example, when calling No. 1 of the mobile handset 4 from the wired telephone 5, the caller of the wired telephone 50 performs a dialing operation to call number 300 in the same way as a general telephone. At this time, the caller using the wired telephone 5 does not know where Nα1 of the mobile handset 4 is, and there is no need for him to do so. When a user dials the number 300, this signal passes through PBX 1 and enters RCU 2. As mentioned above, the RCU 2 performs the registration operation based on the monitoring result for No. 1 of the mobile handset 4 to register No. 300, that is, Nα.
It is already known which CF2's service area the mobile handset 4 is in and is managed by that CF2.

The RCU 2 selects the CF2 that is managing the mobile handset 4 of Nα1, and calls the mobile handset 4 of No. 1 by radio via this CF2. A connection is established in this way, and a call is possible.

Nα1 of mobile handset 4. When talking between two Na devices, when Na 1 dials the number 400, the nearby CF 2 receives this wireless signal and connects the connection line 7.
The connection is extended to RCU2 via connection line 6, and then to PBXI and selects No. 400 from PBXI. Similarly to the above case, the connection is extended to RCU2 via RCU4゜CF2.
It is connected to the mobile handset 4 of No. 2, and mutual communication is possible.

In this way, in this system, the mobile handset 4 that moves freely can receive calls and can also make calls from the mobile handset 4 in exactly the same way as a wired telephone.

Now, as already mentioned, it is necessary to associate this extension number with the mobile handset number. In the case of a wired system, it is sufficient to simply wire metal wires, but for wireless telephones such as this system, which can be moved freely, the correspondence between extension numbers and mobile handset often needs to be changed. Therefore, it is impossible to use metal wire wiring, so another method must be used.

The correspondence between wired extension number and mobile handset ID number is RC.
□ Processed within the U device. - As an example, assume that the wired extension number 300 is assigned to the NAL mobile handset, the number 400 is assigned to Nα2, and the number 500 is assigned to Nα3.

These correspondence tables (hereinafter referred to as link tables) are I
It is necessary to write it into non-volatile RAM, which is C memory. This number is set when the device is installed, but in the past, the data loader 8 was temporarily connected and operated for this number setting.

This data loader 8 can be used for other devices as well, and is usually carried by construction and installation contractors. Naturally, the data loader 8 may be incorporated in each system, but the above configuration is common because it is used infrequently and costs are high.

In this way, in the conventional system, the data loader 8 was used to set the number, so when replacing a mobile handset or changing the extension number, the contractor had to bring the data loader and change the number. There were some inconveniences, such as not being able to respond immediately. Also, because the data loader was specially made, maintenance costs were high.

(3) Purpose of the Invention In order to eliminate these drawbacks, the present invention eliminates the data loader and automatically creates a link table that associates extension telephone numbers and mobile handset IDs within the RCU. This provides a line number setting method for a radio line control device.

(4) Structure and operation of the invention In order to achieve this object, the line number setting method of the radio line control device according to the present invention is designed to connect a plurality of mobile handsets that communicate using radio, A function that automatically creates a correspondence table between wired telephone numbers and mobile handset ID numbers in a wireless line control device that performs overall control between one or more connecting devices and wired telephone lines. is incorporated into the radio line control device.

The present invention will be explained in detail below.

2 to 4 show examples of the present invention. A first embodiment is shown in FIG. In Figure 2, the RCU memo IJ M (x
) shows how the mobile handset ID is registered.

In the example shown in Figure 2, number 3 is stored in memory 1 (M(1)) and number 2 is stored in memory 1 (M(1)).
No. 1 is registered in (21), and No. 2 with a 3(M(+)) ratio is registered. This registration method is to store the information in the memory in the order of registration starting from the mobile handset 4 at the time of initial setting of the device. These memories M, . . . are connected to the extension connection terminals A, M, 2, . is associated with B, and M(3) is associated with C. By connecting the extension number wires of 300.400° and 500 to these extension connection terminals A, B, and C, extension number 300 is connected to memory 1.
It will be associated with the mobile handset 4 of No. 3 having the content of (M(+)). During normal calling/receiving, the device operates while always referring to this link table.

In the second embodiment, the numbers set in the order of registration in FIG. 2 are further automatically processed internally and rearranged in descending order of numbers. By rearranging them in ascending order, it becomes much easier to understand. Figure 3 shows this situation. FIG. 4 shows the procedure for rearranging the numbers in ascending order. The extension number 300 connected to extension connection terminal A of RCU2 is stored in memory 1 (
This indicates that it corresponds to the mobile handset 4 with the content of M(+)). If all the mobile handsets 4 connected to the system are registered first, the link table will remain unchanged thereafter.

As described above, it has been found that the present invention does not require a data loader and can easily perform number assignment.

Next, referring to the flowchart of FIG. 4, the operation of sorting the registered data will be explained.

In Sl, the number of data N and variables 1. J and K are set.

In S2, I=2. Let J=1.

In S3, it is determined that M +11 > M (11), and an output of N or Y is output depending on the result.

In S4, when there is a Y output in S3, =M(71) is set.

In S5, M(J, is set to M(, , ).

In S6, M, 1. Let be K.

In S7, at the end of S6 and by the N output of S3, I is set to (
1+1).

In S8, it is determined that N<1, and depending on the result, an output of Y or N is output, and when the output is N, the process goes to step S3.

In S9, when Y output is obtained in S8, J is changed to (J+
1).

In SIO, ■ is set to (J+1).

In Sll, determine N<J, and depending on the result, choose Y or N.
output, and when the output is N, go to step S3, and output Y.
When it is output, the operation ends.

Although the above explanation has been about an extension telephone, it goes without saying that the same function can be achieved even if the telephone is connected directly to a public communication line instead. Furthermore, although the explanation has been given on rearranging the IDs of the mobile handsets 4 in ascending order of numbers, it is also possible to rearrange the extension numbers or public communication line numbers on the input side in ascending order of numbers or vice versa.

The same applies to phones in which the mobile handset is not wireless but can be moved by plugging into and disconnecting from a wired outlet, and phones in which the connection of the mobile handset 4 is fixed but the ID of the phone can be changed using an IC card, etc. .

The operation of the RCU will be explained with reference to FIG.

To register the position of the R station 4, the RCU 2 receives a position registration signal from the R station 4 via the CF 2 and the CE interface circuit 2-2, and sends the signal to the R station for the corresponding number table.
This is done by storing it in AM 2-8. The location registration signal is determined according to a transmission procedure determined between the R station 4 and the RCU 2', and uses, for example, an MF signal. Therefore, the MF receiver circuit 2-4 is required to receive this. However, this is not the case as long as the location registration signal can be received completely and promptly other than the MF signal. Information sent from R station 4 is sent to CE
Recognized by interface circuit 2-2 and stored in RAM 2-8
Correspondence number table stored in (Figure 2).

With reference to FIG. 3), the corresponding PBX extension interface circuit 2-1 is selected and a call is made to the PBX extension. Incoming calls from PBX extensions are sent to PBX extension ink face circuit 2-1.
, selects the corresponding CE interface circuit 2-2 by referring to the corresponding number table, and transmits the incoming signal to the R terminal via the CE3.

The above operations are controlled by software in the program storage ROM 2-7 under the main CPU circuit 2-5.

The data loader interface circuit 2-3 is used for mutual signal transmission with the data loader 8. The communication path control circuit 2-6 controls each circuit 2-1.2-2.2-3.2-4 under the control of the main CPU circuit 2-5.

FIG. 6(a) shows RCU2-C related to position registration of R station 4.
It is an operation flow between E3-R and 4.

After receiving the location registration request signal from the CE 3, the RCU 2 creates a corresponding number table. In principle, signals in the wired section comply with the DID protocol, and include the following signals.

(1) DC lossiness (polarity reversal/depolarity) (2) DC loop (open/closed) (3) MF double trust The signal in the line section has a configuration as shown in FIG. 6(b).

As for the frequency, a 250 MHz band is used in the CE3 to R4 direction, and a 400 MHz band is used in the R4 to CE3 direction, and is divided into 19 control channels and 45 communication channels.

Figure 7 shows PBXl-RCU2 regarding calls originating from R station 4.
It is an operation flow between -CE3-R and 4. The corresponding PBX interface circuit 2-2 from the corresponding number table at the time of
Select.

Figure 8 shows PBX-RCU-C regarding incoming calls from PBX.
It is an operation flow between E-R. At point A, a CE interface circuit is selected from the number correspondence table.

(5) Effects of the Invention As explained in detail above, in the present invention, the procedure for creating a link table is pre-installed in the RCU, so there is no need to carry around a data loader as in the past. Therefore, it has the advantage of being able to respond to number changes immediately and reducing total costs.
